We studied flow characteristics and response to norepinephrine, Chlorpromazine and gastrin in 22 canine gastroepiploic artery (GEA) recirculation model. The GEA flow was obtained by a drip for a minute, opening the end of pedicle GEA. Furthermore, aortic flow and celiac arterial flow were measured by magnetic flow probe. The administration of chlorpromazine, vagostigumine, and gastrin induced a increase in both celiac arterial flow and pedicle GEA graft flow. Especially, the administration of gastrin induced significant increase in GEA flow and celiac arterial flow. Furthermore, adding norepinephrine step-wisely, the GEA flow increased remarkably, in spite of decrease of celiac arterial flow. This response was caused from difference in vascular resistance among celiac arterial branches. Therefore, the pedicle GEA graft has homogenous response as same as intact GEA that perfuses stomach, because its flow was affected by adrenergic and parasympathetic agent, alpha-blocker and gastric hormone.

A method is described for the partial purification of hog's antral gastrin by gel filtration and ion-exchange chromatography. Gastrin was assayed by its effect on the pH of the effluent fluid from the perfused lumen of the stomach of the anaesthetized rat. The latency of the response to gastrin given intravenously was shorter than the latency to a similar dose of histamine. The response to gastrin injected into the arterial circulation of the stomach appeared sooner than the response to gastrin injected intravenously. Iproniazid and aminoguanidine potentiated responses to gastrin. Incubation in vitro with monamine oxidase or diamine oxidase did not inactivate gastrin. Chlorpromazine and bromolysergic acid diethylamide, in doses which enhance the effects of histamine on acid gastric secretion, did not affect responses to gastrin.
